Arrma Kraton for sure.. Shim the diffs, get the aluminum servo mount and make a tower to tower brace.. After that just your normal replace/upgrade as you break things.. Its a beast.. Hands down a beast. They rip and as long as you turn down the throttle till you get use to it on 6s you should be fine. Only other thing I see happen to them is the stock bearings. If you water blast them then they will go out on you kinda quick. While running it ya might wanna get some bearings. I haven't seen hardly any other rc take such a beating when set up right.. The tekno et48.3 and on the smaller side the proline Mt are both tough as nails also.. But same deal they need a little aftermarket love to be send it ready. For the price though is I'm not sure you can beat a v3 kraton.. No matter what you choose just know in my opinion those 3 are pretty high up on the gettin it down scale.
